Bits 2, 1, and 0—Clock Select (CKS2, CKS1, and CKS0): These bits select one of eight internal
clock sources obtained by dividing the supporting-module clock (ø
Bit 2: CKS2

From the clock source frequency, the resolution, period, and frequency of the PWM output can be
calculated as follows.
If the ø
for each clock source are as shown in table 10.3.
